' lowing is aspecification.

My invention pertains to improvements in what may be termedline-spacers.

It has for its object to accomplish that end in a simple, expeditious,and effective manner; and it therefore consists of the featuressubstantially as hereinafter fully disclosed, and particularly pointedout by the claims.

In the accompanying drawings, illustrating the preferred embodimentof'my invention, Figure 1 is a plan view thereof. Fig. 2 is a sideelevation of the same. Fig. 3 is a vertical longitudinal sectionproduced through the spacing-finger-actuating bar or,

rack. Fig. 4 1s a corresponding section taken through thespacing-bar-carrying slide and adjunctive parts. tion taken through saidslide and its manually-moved contrivance. Fig. 6 is an enlarged detachedperspective view of the finger-actuated bar or rack. Fig. 7 showsdisassembled detached views of the locking-nuts for controlling theextent of the movement of the rack-bar. Fig. 8 is also a detachedperspective ofthe contrivance for manually manipulating therack-bar-enga ing pinions.

Fig. 9 is a transverse section pro uced through gitudinal rack or track2.

the point of connection between the spacingfin er-attaching stem or postofthe aforesaid sli 'e or carriage.

In carrying out my invention I provide in connection with a suitablecopy-holder, designated generally as 1, preferably of my own devisingand which may form the subjectmatter of a separate application, a fixedlon- Said rack or track is connected, preferably as shown, by endbrackets 3, to said holder as to occupy a plane or position below thelatter, and arranged in a plane above and a little laterally of saidtrack or rack is a second rack or bar 4, with its 'cogged or racksurface facing downwardly or in a direction opposite to that in whichthe rack or track 2 faces. Said rack or bar 4 is supported near one endin an arm 5, secured to one of the brackets 3, and near its other end inan aperture 6, roduced in the other of said brackets. Sai bar hassecured to its end extending beyond the latter bracket a spring 7, theopposite end of which Fig. 5 is a transverse secbeing for conveniencesecured upon one end of the track 2 and by-a fastening means common toboth said spring and. track, the tension thereof being exerted to impartendwise thrust to said bar, and opposed to which tension is a pin orstop 8, projecting from said bar andstanding normally in contact withone of the brackets 3. The arm 5 has its free end provided with oppositependent flanges 9, between which is received and slides one end of thebar 4, which end of the I latter is split or slotted horizontally, as at10, to receive said end of said arm and permitting such sliding movementof said bar. The

opposite end of said bar has sleeved or in-' serted thereon jam-nuts 1213, engaging screw-threads 14, formed upon the corner edges of the bar4. It is observed that by the requisite manipulation of said nuts theirposition may be readily adjusted for varying the stroke of thespacingfinger-controlling bar 4, accordingto the extent of space overwhich it may be desired to move said finger, as will be readilyappreciated. Said bar or rack 4 is equipped at its extreme re'ar endwith an upstanding fixed finger-piece 16 for its convenient actuation.

' A slide or carrier 17 which may be of the form or character shown, ismounted to be freely moved upon parallel guide-rods 18, passingtherethrough'and fixed to the brackets 3, and upon a suitably-equippedstem or post 19, carried by said slide or carrier, is a spacing-finger20, adapted to extendacross and rest upon the leaves of the memorandumbook or other matter which may be placed upon the holder 1 and fromwhich it may be required to copy notes. Of course the spacing-fin er isdesigned to immediately underlie the ine of matter or stenographic notesit may be desired 'to be copied. Said stem or post 19 is inserted into avertical socket or aperture 19, extending through the slide 17, and isprovided with a set or holding screw 20, screwing into a horizontalthreaded aperture 21, intercepting said aperture or socket 19 andengaging or impinging said stem for its retention in place. Said. slideor carrier has also freely passing horizontally therethrough ahand-wheel-equipped' shaft 22, which has fixed thereto two fine toothedor cogged pinions 23 24, engaging the rackbars or tracks 2 4,respectively, one, however, being of a greater diameter than the otherand arranged or connected for conjoint action, as" presently seen. Thesmaller pinion 23, which is actuated as the manually-actuated bar 4 isoperated, has a slip-ratchet coupling or connection with the largerpinion 24, which travels upon the track 2, and the interactingratchet-faces of said ratchet connection 25 between the two pinions arerendered capable of such slip connection or engagement by means of aspring-pawl arrangement 26 as, the manually-actuated bar 4 is released.The shaft 22 is also equipped with a spring 27, interposedbetween the'slide'17 and the pinion 24, and whereby by pulling outward upon thehand-wheel of said shaft said spring may be duly compressed and thepinions 23 24 be thus moved laterally or outward, thereby permitting thedisengagement of these pinions from their rackbars. This adjustment ofparts permits the quick returning of the finger-bearing slide or carrierto its initial position when the latter has been moved to its finalposition. Said spring 27 permits the automatic lateral movement orreturn of the pinions to their normal position when outward lateralpressure is removed from the shaft 22, bearing said pinions, as isapparent.

It is noted that when it may be desired to i move the spacing-finger 20over the page of the memorandum-book for the guidance of the copyist itis only required that the requisite pressure of the finger be applied tothe piece 16 when the rack 4 will be moved rearward, which will ofcourse engage and partially turn its engaging pinion 23 and accordingly,through the pinion 24, traveling upon the track or rack 2, transmitmovement to the carrier or slide 17, in turn effecting the adjustment ofsaid spacing-finger 20.

The various other adjustments of the several parts of my invention areapparent from what has already before been stated, it is believed.

It will be apparent in operation that the copyists note-book beingsuitably held in place upon the holder 1 by means not shown, and so thatthe lining or spacing bar 20 may just underlie the initial line ofmatter for transcribing or copying, as well understood, said initialline of matter having been copied the operator suitably presses thefinger-piece 16, whose engagement with the rack-bar 4 actuates thegearing, transmitting move ment to said spacingbar, accordingly movingthe latter so as to take a position just under the next line below, thisactuation of parts being repeated at the required intervals throughoutthe copying operation until the entire page of the note-book has beencopied. The manlpulation of the requisite parts, as

at 23, &c., is now resorted to, as above noted,

to permit the returning manually of the spacing-bar 20 to its initialposition, as is readily appreciated, when of course another leaf or pageof matter may be turned over and brought under the spacing-bar and thecopying thereof be proceeded with, and so on.

I claim 1. A device of the character described, comprising practicallyopposed racks, one adapted to be manually actuated, a slide or carriersuitably mounted in position, pinions adapted to engage said racksrespectively, means carrying said pinions from said slide and aspacing-finger carried by said slide.

2. A device of the character described, comprising opposed racks, amanually-actuated rack stroke-controlling means therefor, a slidecarrying a spacing-finger, and pinions engaging said racks respectively,and means carrying said pinions from said slide.

3. A device of the character described, comprising opposing racks, oneequipped with a manually-actuated. finger-piece, a spring adapted todeliver its pressure upon the manually-operated rack, pinions cngagingsaid racks respectively, a slide carrying a spring-linger, and a shaftcarried by said slide and bearing said pinions.

4. A device of the character described, comprising opposed racks, oneequipped with means for its manual actuation, a slide earrying aspacing-finger, pinions engaging said racks respectively, and having aslipratchet connection therebetween, and a shaft bearing said pinionsand carried by said slide.

5. A device of the character described, comprising opposed racks, oneadapted to be manually actuated and equipped with stroke-controllingjam-nuts, a slide carrying a spacing-finger, pinions adapted to engagesaid racks respectively, and a shaft carried. by said slide and bearingsaid pinions.

6. A device of the character described, comprising opposed racks, oneadapted to be manually actuated and held under springpressure, a slidecarrying a spacingdinger, pinions adapted to engage said racksrespectively, means for throwing said pinions out of normal position anda shaft journaled in said slide and equipped with a spring deliveringits tension to automatically restore said pinions to normal position. i

In testimony whereof I aflix my signature in presence of two subscribingwitnesses.
